21世纪海上丝绸之路战略支点是指承载我国与沿线国家经贸、科技、文化合作功能的空间区域。近年来，我国与沿线国家在经贸合作园区、交通基础设施建设等方面开展了广泛合作，取得了良好效果，但也存在顶层设计不清晰、空间布局不合理、合作方式较单一、合作层次不丰富等问题。本研究以围绕“五通”加强战略支点建设为研究目标，在我国对外贸易数据分析为基础，利用层次分析法和德尔菲法，提出了战略支点建设的重点区域和建设模式，并从推进经贸合作区建设、加强科技文化交流、深化地区与行业合作等方面提出了政策建议。

The strategic pivot of the 21st-Century Maritime Silk Road refers to China's policy of bolstering bilateral trade, science and technology, and cultural cooperation between itself and the silk road countries. In recent years, a broad range of fruitful cooperation has become a reality between China and the silk road countries in constructing economic and trade cooperation zones and transportation infrastructure. But the outcomes can be improved by addressing unclear top-level planning, less than optimal spatial layout for projects, and lack of intensive multilevel engagement between China and its partners. This study aims to strengthen the strategic pivot around the basic goal of "five-links" by analyzing China's foreign trade data and identifies the key areas and construction modes of strategic pivot with AHP and Delphi methods. This paper also advances some policy recommendations for the 21st-Century Maritime Silk Road such as enhancing economic and trade cooperation zone construction, scientific and cultural exchange, and regional and industrial cooperation.
